Hazards identification:
Compressed gas. In high concentrations
may cause asphyxiation
Skin / Eye contact:
Immediately flush eyes thoroughly with
water for at least 15 minutes. In case of cold burn spray with water for at
least 15 minutes. Apply a sterile dressing. Obtain medical assistance.
Inhalation:
Low concentrations of CO² cause
increased respiration and headache. In high concentrations may cause
asphyxiation. Symptoms may include loss of consciousness and mobility.
Victim may not be aware of asphyxiation. Relocate victim to an
uncontaminated area wearing self contained breathing apparatus. Keep
victim warm and rested. Call for emergency medical assistance. If
breathing stops apply artificial respiration
Ingestion:
Ingestion is not considered a route of
exposure.
Specific Hazards:
Exposure to fire may cause cylinders
to rupture or explode. Non-flammable gas.
Hazardous combustion:
None.
Suitable extinguishing media:
All known extinguishers can be used.
Specific methods:
If possible, stop flow of product. Move
cylinder away or cool with water from a protected position.
Special protective equipment
For firefighters:
In a confined space use self-contained
breathing apparatus.
Personal protection:
Evacuate area. Ensure adequate air
ventilation. Wear self-contained breathing apparatus when entering area
unless atmosphere is proved to be safe.
Small release:
For a leaking cylinder, try to stop
release by closing the cylinder valve if safe to do so.
Major release:
Evacuate the area immediately. Frost
will appear on the surface of the cylinder. The cylinder should be left to
completely discharge and Broadman Ltd should be contacted.
Environmental precautions:
Where possible prevent from entering
low lying areas where its accumulation can be dangerous.
Clean up method:
Ventilate area.
Handling and storage:
Cylinders should be secured when
stored or in use. Only use cylinders when in the upright position. Water
ingress into the cylinder must be prevented. Do not allow back feed into a
cylinder. Cylinders which have been exposed to flooding in cellars, must
not be used, and Broadman Ltd contacted for collection. Do not store
cylinders next to a direct heat source. Keep cylinders below an ambient
temperature of 50˚C. Failure to do so may cause pressure build up in the
cylinder and the bursting disc to operate. Store in a well ventilated area, if
this is not possible conduct a confined space risk assessment. Use only
properly specified equipment which is suitable for the product, its supply
pressure and temperature. Only open the cylinder valve when it is
connected to the equipment. Open and close the valve slowly. Close the
cylinder valve when not in use.
Personal Protection:
Ensure adequate ventilation to keep
below exposure limits. Wear eye protection to EN166 when using gas.
Wear leather safety gloves and safety shoes when handling cylinders.

General Information
The hazard of asphyxiation is often
not stressed enough when handling cylinders, especially in confined
spaces. Keep containers in well ventilated area. Contact with the liquid
may cause burns or frost bite. For beverage dispense only. Details given
above are believed to be correct at the time of publishing. Whilst every
reasonable care has been taken in preparing this data sheet, no liability for
injury or damage resulting from its use or interpretation can be accepted.
